(b) As used in this section: "Bump fire stock" means a butt stock designed to be attached to a semiautomatic firearm and designed, made, or altered to increase the rate of fire achievable with such firearm by using energy from the recoil of the firearm to generate a reciprocating action that facilitates repeated activation of the trigger. "Multiburst trigger activator" means: (1) A device that simulates automatic gunfire by allowing standard function of a semiautomatic firearm with a static positioned trigger finger or a device that fires multiple shots with the pull and release of the trigger; or (2) A manual or power-driven trigger activating device constructed and designed so that when attached to a semiautomatic firearm it simulates automatic gunfire. "Trigger crank" means any device to be attached to a semiautomatic firearm that repeatedly activates the trigger of the firearm through the use of a lever or other part that is turned in a circular motion, but does not include any firearm initially designed and manufactured to fire through the use of a crank or lever.
